  PHP: a fractal of bad design

Preface I’m cranky. I complain about a lot of things. There’s a lot in the world of technology I don’t like, and that’s really to be expected—programming is a hilariously young discipline, and none of us have the slightest clue what we’re doing. Combine with Sturgeon’s Law, and I have a lifetime’s worth of stuff to gripe about. This is not the same. PHP is not merely awkward to use, or ill-suited for what I want, or suboptimal, or...

  40+ Techniques to enhance your php code

1. Do not use relative paths , instead define a ROOT path Its quite common to see such lines : 1require_once('../../lib/some_class.php'); This approach has many drawbacks : It first searches for directories specified in the include paths of php , then looks from the current directory. So many directories are checked. When a script is included by another script in a different directory , its base directory changes to that of the including script. Another issue , is that when a script is being ru...

  PHP Security

1. IntroductionWriting PHP applications is pretty easy. Most people grasp the syntax rather quickly and will within short time be able to produce a script that works using tutorials, references, books, and help forum forums like the one we have here at PHP Freaks. The problem is that most people forget one of the most important aspects that one must consider when writing PHP applications. Many beginners forget the security aspect of PHP. Generally, your users are nice people, they will...

  CSS3 Animation With jQuery Fallbacks

In today's post, we'll be taking a look at how you can use CSS3 transitions to power your application's animations with jQuery's .animate() method as a fallback where transitions aren't supported. The benefit of transitions is that unlike JavaScript based animations, they're hardware accelerated in certain browsers and mobile devices, resulting in a potentially smoother overall animation than you would normally experience. In a lot of cases your code will work seamlessly with the solut...

  Best “must know” open sources to build the new Web

Here the dump of my ultimate collection of online Web development resources and directory, oriented for the Front-End user Interface (UI). HTML5 and all related open standards are moving fast, but for now, building a whole Website/WebApp on top of that can be very inconsistent, especially across various browsers experiences.   So… how to embrace new awesome web technologies ? Now, as Web Developers and Designers, we have to build on top of more stable framework. It’s her...

  True Scala complexity

Update 2: Sorry for the downtime. Leave it to the distributed systems guy to make his blog unavailable. Nginx saves the day.It’s always frustrating reading rants about Scala because they never articulate the actual complexities in the core language.Understandable—this post is intended fill that gap, and it wasn’t exactly easy to put together. But there’s been so much resistance to the very thought that the complexity exists at all, even from on up high, that I thou...

  Signs that you're a bad programmer

1. Inability to reason about codeReasoning about code means being able to follow the execution path ("running the program in your head") while knowing what the goal of the code is.SymptomsThe presence of "voodoo code", or code that has no effect on the goal of the program but is diligently maintained anyway (such as initializing variables that are never used, calling functions that are irrelevant to the goal, producing output that is not used, etc.)Executing idempotent functions multiple times (...

  Why (offset, limit) is slow in database select?

Starting from a problem Five years ago when I was working at Tencent, I found that MySQL request speed was very slow in the pagination scenario. With only 100,000 data, a select query on a single machine took about 2-3 seconds. I asked my mentor why, and he asked in return, "In an indexing scenario, what is the time complexity to get the nth largest number in MySQL?" The pursuit of the answer Confirming the scenario Assuming there is an index on the "status" column, a query like "select * from t...
